"There was a cold pressure system on Saturday which brought rain with it," duty forecaster Anna Forrest said.

The Midlands were also affected by heavy downpours on Saturday, with minor flooding between Ross and Campbell Town.

Motorists were advised to not proceed through flooded roadways.

"We are in winter now, so people need to realise that the road conditions will be different and to drive accordingly," Sergeant Stewart said.

SES North-West regional manager Wayne Richards said his organisation had only received one callout during the storms over the weekend, for a single-vehicle rollover near Renison Mine on the West Coast.

Mr Richards said it was reported at 12.30pm on Saturday and the SES helped local police with traffic management.
